Sorry, but exactly where did you get the idea that DS V4 runs entirely on Huawei?

I asked DS itself and it denied this. It says: 'Nvidia chips are absolutely used for DeepSeek V4. The reality is a pragmatic "both-and" strategy, not an "either-or."'

And based on the DS V4 technical report (https://huggingface.co/deepseek-ai/DeepSeek-V4-Pro/blob/main...), it is mentioned that:

  We validated the fine-grained EP scheme on both NVIDIA GPUs and HUAWEI Ascend NPUs platforms. Compared against strong non-fused baselines, it achieves 1.50 ~ 1.73× speedup for general inference workloads, and up to 1.96× for latency-sensitive scenarios such as RL rollouts and high-speed agent serving.

It mentions that Nvidia is still used. It doesn't even mention that Huawei chips are used in production — only in testing and validation, yes.

Bro, seriously?
